MEASURING-MACHINE.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed July 31, 1903. Serial No- 167,716.

To all whom it may concern:

Be it known that I, FRANKLIN J AY PERKINS, of \Voburn, county ofMiddlesex, and State of Massachusetts, have invented an Improvement inMeasuring-Machines, of which the following description, in connectionwith the accompanying drawings, is a specification, like characters onthe drawings representing like parts.

This invention relates to measuring-machines of the class shown anddescribed in United States Patent No. 329,597, dated November 3, 1885,wherein a registering mechanism is operated by means of a series ofmeasuring-wheels which are raised into operative connection with saidregistering mechanism by the hide, skin, or other surface to bemeasured, which latter is passed between the measuring-wheels and abed-roll cooperating therewith. In machines of the class referred toprovision is made for adjusting the machines to measure hides or skinsand like material of different thickness, and this is accomplished inthe said machines by adjusting the toothed segments individually withrelation to their measuring-wheels, which is objectionable, as it notonly requires considerable time to effect the adjustment, but also onaccount of the liability of error arisingfrom the individual adjustment.

The present invention has for its object to overcome the defects andobjections above referred to and to providea measuring-machine of thisclass which can be adjusted to measure stock of different thicknesssubstantially 4 in an instant; and to this end the machine is providedwith an adjustable bed-roll eccentrically mounted, so that the saidbed-roll may be raised and lowered with relation to the toothed segmentsto adjust the machine to measure stock of different thickness withoutdisturbing the toothed segments, as will be described, and with meansfor locking the cocentrically-mounted roll in its adjusted position.

Figure 1 is a front elevation of a measuring-machine embodying thisinvention; Fig. 2, a side elevation of the machine shown in Fig. 1looking toward the left, and Fig. 3 a detail in section to be referredto.

The main features of the measuring-machine herein shown are and may bethe same as shown and described in the patent referred to. Thesefeatures consist, essentially. of a series of measuring-wheels at,having their shafts 5 supported by levers 0, connected by links alwithlevers e, which support the shafts f of toothed segments 9, whichcooperate with and are rotated by toothed hubs or pinions not hereinshown, but which are fast to the measuring-wheels a.

The toothed segments g are connected with the registering mechanism,comprising the pointer h and dial i, by cords or chains 1', passed overpulleys it, carried by levers Z, which are connected by intermediatelevers m with a main lever 01., which is connected by a flexibleconnection or cord 0 with a lever p, which is geared or otherwiseoperatively connected with the pointer h. The measuring-wheels a arenormally disengaged from the segmentsg and rest upon a bed-roll 5, whichin accordance with this invention is vertically adjustable, which may beaccomplished as herein shown, and for this purpose the bed-roll isprovided with journals 6, which are extended into bushings orbearing-sleeves 7, mounted to turn in suitable boxes 8, supported by theupright side frames 9 of the machine. The journals 6 are locatedeccentrically in the bushings or sleeves 7, and provision is made forturning the said sleeves in their boxes, so that the bed-roll andmeasuring-wheels resting thereon may be raised and lowered with relationto the toothed segments. This result may be accomplished, as hereinshown, by means of cranks or arms 10, secured to or forming part of thesleeves 7, which cranks or arms may be provided with handles 12.Provision is also made for locking the bedroll in its adjusted position,and for this purpose each of the arms or cranks 10 is provided withscrew-threaded pin or projection 14, which is extended through a slot 15in a bracket or bar 16, attached to a side frame 9, and is engaged by anut 17, which serves to clamp the crank or arm to the bracket 16. Thebrackets or slotted bars 16 may, if desired, be provided with suitableindications 30, (see Fig. 3,) such as scale marks or graduations, sothat both bushings 7 may be turned the same amount when it is desired toadjust the bed-roll.

From the above description it will be seen that the bodily movement ofthe bed-roll'effects a bodily movement of all of the measuring-Wheelssimultaneously, thereby enabling a measuring-machine embodying thisinvention to be adjusted for stock of different thickness substantiallyin an instant and without disturbing the toothed segments or the partsof the machine connected with the registering mechanism.

I have herein shown one means for effect ing the adjustment of theeccentrically-mounted bed-roll; but I do not desire to limit myinvention in this respect.

I claim-- 1. In a measuring-machine, in combination, a registeringmechanism, a plurality of bodilymovable measuring-wheels, mechanism forconnecting said measuring-wheels with said registering mechanism, astationary frame, and a bed-roll cooperating with said measuring-wheelsand eccentrically mounted in said stationary frame to effect bodilymovement of said bed-roll toward said measuring-wheels, for the purposespecified.

2. In a measuring-machine, in combination, a bed-roll, sleeves orbushings in which said roll is eccentrically mounted, mechanism forrotating said sleeves or bushings to elfect bodily movement of the saidroll, and means to lock said bed-roll in different positions into whichit is moved, substantially as described.

3. In a measuring-machine, in combination, a bed-roll, sleeves orbushings in which said roll is eccentrically mounted, cranks or armsattached to said bushings or sleeves, and means to secure said cranks orarms in their adjusted positions and thereby lock said bed-roll in itsadjusted positions, substantially as described.

4. In a measuring-machine, in combination, a bed-roll, bearings in whichsaid bed-roll is eccentricall y mounted, means for rotating saidbearings to cfi'ect bodily movement of said bed-roll and means to locksaid bed-roll in different positions into which it is moved,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FRANKLIN JAY PERKINS.
